"Red, white and black mangroves are tropical ecosystem trees that exist between
sea and river, in a unique condition of brackish water — the halfway point
between freshwater and saltwater. In this transition zone that’s subject to
tides, the plants have adapted by developing their own structures to breathe
underwater and better cling to the muddy soil by using prop roots. Mangrove
forests can be found along almost the entire Brazilian coast.
Considered nurseries for marine life, species that eventually migrate out to
sea, mangroves are key to the fishing supply chain, both small-scale and
industrial.
Just like any other ecosystem, mangroves provide natural services that people
benefit, from such as carbon sequestration — up to 15 times more than forests
on a hectare-for-hectare basis — and protection against the impact of sea
waves, which can cause erosion in places where the native vegetation has been
stripped away. However, these biodiverse areas are increasingly threatened by
urbanization, invasive exotic species, sewage disposal, fires, and climate
change.
Due to the inevitable rise in sea levels and the increase in the frequency and
intensity of storms, coastal cities need investments and adaptation measures
focused on reducing risks and minimizing the impacts caused by extreme weather
events.
According to projections by the United Nations’ Intergovernmental Panel on
Climate Change (IPCC), sea levels are expected to rise by 20 centimeters (8
inches) by 2050 if the increase in the global average temperature remains below
2° Celsius (3.6° Fahrenheit) above pre-industrial levels.
It may seem a small increase, but it will cause greater coastal erosion
problems and indicates that future flooding will reach higher places that
historically have never flooded, affecting more people and causing more damage.
Rising sea levels are associated with ocean warming, which in turn interferes
with rainfall, causing stronger weather events."
